` new and novel means for tearing out a bag end,.

which can be quickly and easily operatedby hand. Another object is to provide means for tearing out an end of a bag along straight lines, in order that all of the material may be dropped out of the bag, andwaste oi material thereby prevented;

Still another object is to provide means for tearing open the end of a bag, which are adapted to be used in a wide range of bags, containers, and the like, which may be installed at a relatively low cost.

Other objects and advantages of the invention will be apparent during the course oi the following description.

In the accompanying drawing forming a part of this specication:

Fig. 1 is anillustrative embodiment of my`v invention, as applied to avalve bag ofthe gusset type, showing a perspective view of the top of the bag in open position, before the flaps are pasted together.

Fig.' 2 shows the same bag end after the naps,

have been pasted together, and

Fig. 3 is a. perspective view oi a bag drawn to a smaller scale, illustrating the manner of tearing the top end off.

The invention disclosed herein is adapted to be used on containers, envelopes,`bags and the like, oi many diierent sizes, shapes, and dimensions. I have chosen, however, to illustrate my invention as applied to a valve bag of the gusset type as disclosed in United States Letters Patent NumberY 1,985,326, issued to me on ,December 25, 1934, which may be made from ordinary plaated material, formed by simple folding and pasting operations. This type of bag is adapted to package heavy, iinely divided material such as cement, plaster, gypsum, and other heavy materials.

The numeral I Ivindicates a bag formed of suitable material of several plies. such as heavy manila or kraft paper, having wide sides I2 and I3, joined l by narrow sides, Ill'and I5, the upper ends of the wide sides I2 and I3 form respectively horizontal iiaps I2@ and I3a, while the upper ends of the narrow sides I4 and lform respectively short flaps I4a and lia. The means for tearing open the top end of the bag I I for exposing the contents therein, comprises a string or cord I6, disposed 1931, serial No. 192,525 (ci. 229-66) horizontally in a generally U shaped position, having its ends Ita and I6b secured to the bag at the horizontal line of intersection o! the flaps I2a, Ita and the short ap Ila by any suitable means, such as by means of an adhesive or by securing said cord ends between the plies of the `flaps or by any other suitable means.

as above described, and nap I2a is folded over onto the short flaps Ida and lia, and then flap I3a is folded over nap I2a and adhesively secured thereto, adhesive, however, being omitted from the part oi the flaps adjacent to the looped end ,of string I6, thereby forming a bag valve which is adapted to be closed by the weight of material in a well known manner and permits the introduction of a bag filling machine spout. By` this construction, a .part of the looped end of the cord I6, indicated by the numeral Il, is left uncovered from the naps, and permits the same to be grasped by the finger or hand of the user.

After the bag hereinv illustrated has beenlled with heavy material, and it is desirous to empty the contents therefrom, the bag Il is stood in an upright positionas shown in the drawing and the looped exposed end Il of the cord I6 is grasped by the lingers or hand of the operator, who pulls'the cord upwardly and transversely across the-bag. The weight oi the material in the bag permits the bag to remain stationary in an upright position, while the top of the bag, consisting oi folded naps I2aV and Ila is cleanly Atorn from the bag along the horizontal fold lines between the top and sides of the bag, as illustrated in Figure 3. By cleanly severing the 'end of the bag from the sides, all of the contents of the bag, consisting of nely divided material, such as cement and the like, may be removed from the bag by tipping it over an allowing the contents to run out.

It will be seenvtrom the foregoing that there remain no folds, projections, wrinkles, or flaps on the bag which will retain any 0! the material after the bag is inverted, and that the tearing open of the bag is accomplished by the simple operation of merely grasping the exposed looped end I1 of the cord I6 and pulling upwardly and transversely across thebag. The bag openingV device herein disclosed is not limited to use in this particular type of bag, as it is adapted to be used in .various types of containers, bags, envelopes, :and the like.

It will be apparent to those skilled in the art that the invention herein disclosed, may be variously changed, used or modified, without def parting from the spirit of the inventtion or sac- After the cord I6 is suitably secured to the flaps pulling force exerted on the available end of said bag opening means will sever said wall from said bag.

2. A bag adapted to package heavy materials such as cementand the like, comprising, a bag formed of multi-ply material having adplurality of walls, bag opening means including a ilexible looped member disposed inwardly of one of said walls and having its legs secured between the plies thereof and extending along the margins thereof and a ybig'ht portion available exteriorly of said bag,l whereby pulling force exerted on said bight portion will sever said wall from said bag along its margins.

3. A bag adapted to package heavy materials such as cement and the like, comprising, multiply side walls folded over to form a top wall, and bag opening means secured between the plies of the top folds adjacent one side thereof and extending towards the opposite side thereof where a portion of said means is availablewhere by pulling force applied to the available part of said bag opening means will sever the' top from the bag.

4. A 'bag adapted to package heavy materials such as cement and the like, comprising multiply side walls foldedl over to form a top wall, and bag opening means including a -flexible looped member having its legs secured between the top plies adjacent one side thereof and extending 'towards the opposite side thereof and a bight- Aportion available exteriorly of the bag adjacent said opposite side wall, whereby pulling force applied by the user on said' bight portion will sever said top wall from said bag.

5. A bag adapted to package heavy materials such as cement and the like, comprising multi-ply sidewallsfoldedovertoformatopwalbandbsg opening means including a flexible substantially U-shaped lmember having its legs securedv betweenthetoppliesadiacentone sidethereofand extending towards the opposite side wall where its looped portion is available exteriorly of the bag adjacent said opposite side wall, whereby pulling force exerted by the user on the looped portion will sever the top wall from'the bag.

46. A bag adapted to package heavy materials such as" cement and the like, comprising, multiply side walls having their tcp portions flded over to form a substantially rectangularly shaped top wall, and bag opening means secured between the plies of the top wall near a narrow side and extending along the margins of the elongated sure wall'havin'g its legs extending along closure,

wall fold lines, said member being secured to said wall only at the ends of its legs and having a blght portion projecting through said valve opening permittingthe user to grasp it with the hand,

whereby a pulling force may be exerted against the weight of the filled bag, thereby severing said closure wall from the container.

l 8. A bag adapted to package heavy materials such-as cement and the like, comprising side walls folded over to form a top wall, and bag opening means including a' flexible substantially U,shaped member, having its legs secured to the top wall adjacent one side thereof and extending towards the opposite wall where its looped portion is available exteriorly of the bag adjacent said' opposite side wail, whereby pulling force exerted by the user on the looped portion will sever the top wall from the bag.

9. A container of the class described, compriscontainer.
